Answer:

10.5 Inches of snow after 6 hours

Step-by-step explanation:

First you would divide

7/4=1.75

Then you would multiply by 6

1.75*6=10.5

10.5 inches of snow would be the total

Hope this helped! :D

The amount of snowfall in 6 hours, if the amount of snowfall is directly proportional to the time, is 10.5 inches.

In general, the term "proportion" refers to a part, share, or amount that is compared to a whole. According to the definition of proportion, two ratios are in proportion when they are equal.

Given:

In a winter storm, the amount of snowfall is directly proportional to the time,

After 4 hours, a total of 7 inches of snow had fallen,

Calculate the amount of snowfall in one hour as shown below,

amount of snowfall in one hour  =  7 / 4

Calculate the amount of snowfall that occurs in 6 hours,

Amount of snowfall in 6 hours  =  7 / 4 × 6

Amount of snowfall in 6 hours  =  10.5 inches

Answer:

$0.72

Step-by-step explanation:

In order to solve this question we need to know that 1% is one hundredth of something. Another important thing you need to understand is that when we are trying to find n% of y  we multiply just need to multiply "y" by [tex](\frac{n}{100} )[/tex]. In our case we have to find 6% of 12, in other word they are asking as the following "What is $12 times [tex](\frac{6}{100} )[/tex]?". So in order to find the answer we do the following..............

[tex]12 (\frac{6}{100} ) = \frac{(12)(6)}{100} = \frac{72}{100} = 0.72[/tex]

Answer:

x=14

Step-by-step explanation:

Solving the equation x - 10 = 4, the value of x, which is the solution is calculated as x = 14.

Solving an equation simply involves determining the value of the variable in the equation, which is the unknown.

For example, we are asked to solve the equation, x - 10 = 4., what it simply means is that we need to determine what the value of x is in the equation that will make it true. Do the following:

x - 10 = 4

x - 10 + 10 = 4+ 10 [addition property of equality]

x = 14

Therefore, the solution of the equation is x = 14.

Answer:

[tex]Red = \frac{10}{37}[/tex]

Step-by-step explanation:

Given

[tex]Red:Yellow = 2 : 3[/tex]

[tex]Yellow: Blue = 5 : 4[/tex]

Required

Determine the fraction of Red

First, we need to link the given ratios.

Since yellow is present in both ratios, we start by making the ratio of yellow equal in both ratios

Multiply this ratio by 5

[tex]Red:Yellow = 2 : 3[/tex]

This becomes

[tex]Red:Yellow = 10 :15[/tex]

Similarly, multiply this ratio by 3

[tex]Yellow: Blue = 5 : 4[/tex]

This becomes

[tex]Yellow:Blue =15:12[/tex]

At this point, we have:

[tex]Red:Yellow = 10 :15[/tex] and [tex]Yellow:Blue =15:12[/tex]

Combine

[tex]Red:Yellow:Blue = 10:15:12[/tex]

The fraction is then calculated as:

[tex]Red = \frac{Red}{Red +Yellow + Blue}[/tex]

This gives

[tex]Red = \frac{10}{10+15+12}[/tex]

[tex]Red = \frac{10}{37}[/tex]

Answer:

The measure of one of the acute angles is 22 degrees, and the measure of the other acute angle is 68 degrees.

Step-by-step explanation:

The angles of a triangle add up to 180 degrees; we know this by the Sum of Angles of a Triangle Theorem.

Then one angle is marked as a right angle meaning it has a measure of 90 degrees.

Using this information and the labels on the diagram we can set up an equation:

x+3x+2+90=180

Now we can solve for x.

4x+92=180

4x=88

x=22 degrees

The measure of one of the acute angles is 22 degrees.

Now to solve for the measure of the other acute angle.

Subsitute the value of x first.

x=22

(3x+2)=?

3*22+2=68 degrees

The measure of the other acute angle is 68 degrees.

In the right-angled triangle given, the measure of each of the acute angles in the given diagram are:

[tex]\mathbf{22^{\circ}}\\\\\mathbf{68^{\circ}}[/tex]

The triangle given is a right triangle having an angle tat is 90 degrees and two other acute angles given as: x and (3x + 2)

Thus:

[tex]x + (3x + 2) + 90 = 180^{\circ}[/tex] (sum of triangle)

[tex]x + 3x + 2 + 90 = 180[/tex]

[tex]4x + 92 = 180\\\\[/tex]

[tex]4x = 180 - 92\\\\4x =88[/tex]

x = 22

Measure of one of the acute angles is 22 degrees.

To find the second acute angle measure, substitute the value of x

3x + 2 = 3(22) + 2 = 68 degrees

Therefore, in the right-angled triangle given, the measure of each of the acute angles in the given diagram are:

[tex]\mathbf{22^{\circ}}\\\\\mathbf{68^{\circ}}[/tex]

Answer:

volume of Figure B = 75 m³

Answer:

y=4/5x-5

Step-by-step explanation:

to find the slope intercept form (y=mx+b) we must find the slope(m) first. We take the two points given and use the slope formula (y2-y1/x2-x1) take the point (0,-5) as (x1,y1) and the point (5,-1) as (x2,y2).Using the slope formula {-1-(-5)/5-0}. We get the slope equal to 4/5. Now we have y= 4/5x+b.To find b we must choose one point from the given and substitute x and y in the formula we have(y=4/5x+b). I chose (0,-5) so substituting that, (-5=4/5(0)+b), and to finally get b=-5.Now substitute b in the equation y=4/5x+b to get y=4/5x-5.
